What is water resistant 3 atm?

Water resistant 3 atm (atmospheres) means that the watch can withstand splashes of water but cannot be submerged in water. It is equivalent to a depth of 30 meters or 100 feet. This level of water resistance is suitable for everyday activities such as washing hands and light rain, but it is not suitable for swimming, diving, or any activity that involves prolonged exposure to water. It is important to note that water resistance can decrease over time, and it is recommended to have the watch checked by a professional if it is frequently exposed to water.
